A chart-topping singer-songwriter has paid tribute to Onyx Storm in a new song that resonates almost too perfectly with the romantasy series. Although Onyx Storm, the third installment in The Empyrean Series, was released back in January 2025, it remains a major topic of discussion across book communities. That ongoing buzz is largely fueled by the absence of updates on Book 4 and the many new plot threads the third novel introduced. Still, the lack of fresh content hasn’t deterred fans — instead, it’s inspired a wave of creative works across various mediums, as audiences continue to explore and expand the world of The Empyrean Series on their own.
These incredible fan creations—ranging from fanart and fanfiction to dramatic reenactments—shine a spotlight on the most beloved elements of Onyx Storm and reflect the hopes many readers have for the future of the series, including a return to the romantic core that made Fourth Wing so compelling. Naturally, fans often draw inspiration from beyond Rebecca Yarros’ novels, turning to music and other stories to enrich and echo the series’ powerful themes and moments. One artist in particular has captured the hearts of BookTok’s Fourth Wing community: Alex Warren. His latest song struck such a chord with fans that he gave a subtle nod back to them in response.
Alex Warren Gave a Subtle Nod to Onyx Storm With His New Song “Eternity”
Alex Warren gave a heartfelt nod to Onyx Storm and the wider BookTok fandom with his new song “Eternity,” further cementing his growing presence in fandom circles. He first teased a snippet of the track in June 2025 via TikTok, revealing that it would be featured on his upcoming album, slated for release on July 18th. But it was the caption accompanying the post that really caught BookTok’s attention—especially since this isn’t the first time Warren’s music has been linked to Rebecca Yarros’ beloved romantasy series.
The caption reads, “ur telling me he left her with her memory wiped and a ring…”, a direct reference to the emotional ending of Onyx Storm. The line immediately sparked a flurry of excited comments and propelled the popularity of “Eternity” even further. This isn’t the first time Alex Warren has found his music embraced by BookTok—his earlier track “Ordinary” became a favorite for Fourth Wing edits and fanart across platforms when it debuted. Together, these moments highlight Warren’s genuine connection to the BookTok community and the fandom’s deep appreciation for his work. Much of that celebration stems from how perfectly his songs capture the raw emotion of the books, giving fans the freedom to interpret the lyrics in ways that align with their favorite scenes and characters.
Fourth Wing Fans Are Already Embracing “Eternity” — It’s the Perfect Emotional Match
Much like Alex Warren’s last viral hit, Fourth Wing fans have quickly embraced “Eternity” for how seamlessly it aligns with the emotional arc of Onyx Storm and the books that came before. In the snippet Warren shared, the song expresses a deep yearning — the pain of being left behind and the desperate wish to reunite with someone you love. For many fans, myself included, those lyrics perfectly capture Xaden’s mindset at the end of Onyx Storm, when he’s forced to become an asim, leaving Violet—and the “paradise” they built together in Aretia—behind.
That said, some fans have chosen to interpret “Eternity” through Violet’s perspective at the end of Onyx Storm, focusing on the song’s themes of longing and hope. Left behind by Xaden with no memory of their time together and suddenly burdened with the responsibility of becoming the Duchess of Aretia, Violet clings to the hope that she’ll one day reunite with him. For these fans, the “paradise” in the lyrics represents not just a lost love, but a future Violet is now determined to fight for. Both interpretations—Xaden’s heartbreak and Violet’s resolve—beautifully reflect the emotional depth of Onyx Storm, making “Eternity” a fitting and poignant anthem for fans as the series continues.
Alex Warren’s New Song Is the Perfect Addition to Every Fourth Wing Fan’s Playlist
Warren’s upcoming song is a must-add for any Fourth Wing playlist — and not just because it fits Onyx Storm so well. While only a snippet has been released so far, the full version of “Eternity” could resonate even more deeply with fans, offering a soundtrack for past, present, and future moments in Rebecca Yarros’ series, especially once Book 4 arrives. With its soulful lyrics and emotional depth, the song is poised to become a staple for edits and fan creations that explore the complex journey of Xaden and Violet, and the many trials their love must endure.
Even so, Warren’s short snippet has already sparked the imagination of Fourth Wing fans, quickly becoming one of the most anticipated tracks on his upcoming album. It’s a testament not only to the emotional power of “Eternity” but also to the deep bond forming between the artist and the fandom. Warren’s clear excitement and willingness to engage with readers is a joy to witness, highlighting just how passionate and vibrant the Empyrean community has become—especially with the highly anticipated Amazon TV adaptation still on the horizon. “Eternity” captures both the heartbreak and the magic that Onyx Storm left behind, offering fans another outlet to express their creativity while they eagerly await Book 4.
